Yes, many television shows are lacking originality. They either try to duplicate previous shows that worked, or they stick to tried and true formulas, or they regurgitate information that's already been put out. I know there are many fine writers out there who can create wonderfully original shows. Give them a chance.
Westworld has not finished its first season yet, and it is the most original show on television right now. Television is a creative medium that allows writers to work together to explore their creatitivity without the same consequences that filming a movie would have, which is why televison has become more creative and movies less creative.
There are many original ideas, you just have to look for them. Then, you need watch them and give them a chance. There are so many choices on broadcast television, cable, Hulu, Netflix, Amazon, HBO, Showtime, and many more. Also, there is something to be said about programs that use a tried and true formula but then present it in a unique way, making it original.
Westworld Season 2 is not a show lacking originality, because it has a very large budget. In the opening credits, a robot plays the piano. This show had a very unexpected season ending that ended with Anthony Hopkins' character being killed off. It was surprising and even has plot lines on multiple timelines.
